HYDRAULIC MOTOR.

SPECIFICATION frmmg part of Letters Patent No. 223,943, dated January27, Iseo.W

Application filed January 2, 1880. v

To all whom t may concern:

Be it known that I, JOHN A. MYERS, of Louisville, in the county ofJefferson and State of Kentucky, Vhave invented new and valuableImprovements in Hydraulic Motors; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and gnres ofreference marked thereon.

Figure l of the drawings is a representation of the motor operating afan. Fig. 2 is a central sectional view of the motor. Fig. 3 is a bottomview of the valve-box. Fig'. t is a central sectional view of the motor,showing the valves in another position. Fig. 5 is another bottom view ofthe valve-box. Fig. 6 is a plan view of the ante-water-chambers. Fig. 7is a detail view of the double valve'.

This invention relates to that class of hydraulic motors for operatinglight machinery; and the main object is to produce a compact, effective,and cheap hydraulic engine that can beconveniently located foroperating' the fan or fans in dining-rooms in the warm season,

or driving sewing-machines, turning-lathes,

and the like.

The invention consists in means for auto matically operating the valves.

It also consists in connecting the two sets of valves by means to insuretheir simultaneous"`movements in the operation of the piston.

It also consists in the novel combination of the parts, as will behereinafter more fully set forth.

In the annexed drawings I have shown the engine operating a fan in adining-room.

rlhe letter A represents acylinder; B, the upper cylinder-head withcentral opening; O, the stuffing-box 5 D, the hollow piston-rod; E,thepiston-head, suitably packed 5 and F, the valve-box. l

The letter G indicates a pipe suitably `secured and arranged alongsideof the cylinder, forming the water-communication within the The upperportion of the cylinder, above the piston, is charged with water, andthe same discharged through this pipe Gr. It will be noticed that thispipe is connected to the upper surface of the valve-box and registerswith the opening a thereof. (See Fig. 2 of the drawings.)

By means of the iioor or horizontal partition b` the valve-box F isdivided into two stories, the lower story containing the valveoperatingmechanism and the upper story Water-chambers and spaces for thebuttonvalves.

The circular plate H, closely fitting the lower end of the cylinder andresting upon a ledge at the upper end of the valve-box F, forms thelower head to the cylinder, and is provided with two water-passage waysor ports, a b. The passage-way a establishes the communication from thewaterschamber l to the pipe G, and the passage-way 'b establishes thecommunication from the chamber I to the under side of the piston-head.lIhis plate is also provided with a central opening and ange, c, throughwhich the piston d, carrying at its lower end the operating valvedevice, passes, the flange serving as a guide. The valvechamber K isalso divided into two water-compartments by means of the verticalpartitions c (see Fig. 3,) and one compartment is provdded withcharge-openings and the other compartment with discharge openings,arranged in the top wall of the chamber, and induction and eductionpassages arranged on the sides.

ber is arranged, at-one side of the center and at right angles to thecharge and discharge ports, a shaft, M, suitably journaled, so as to becapable of an oscillating motion. To the outer ends of this shaft aresecured the double valve-arms N, provided at their upper ends with thevalves h. These valves are so arranged i'n their respective chambersthat when one is opened, admitting water to its proper passage, thevalve directly opposite in the other valve-chamberis closed, but thevalve arranged on the opposite end of the other arm is opened, allowingthe discharge. (SeeFig. 5.)

The antewater-cham-bers I I areiseparated from each other by means of apartition arranged at right angles to the chambers in thevalve-chambers, and are each provided with the charge and dischargepassageways or ports forming the communications with the upper and lowersurfaces ofthe cylinder, there- Ioo by charging and discharging theWater alter- .nately.

The piston d, for operating the Valves, tits within the hollowpiston-rod, and is provided at its upper end with an adjustable nut, t',and in connection with the screw-threaded cap It, attached to the lowerend ot1 the hollow pistonrod D, acts as coupling means. The lower en dot' the piston d is provided with a pivoted wedge-shaped block, P.acting against the inclined face of the member or arm R, attached to theshaft carrying the valves. The lower end of this block or member P isnotched or recessed to receive one end ot the rod l, encircled by thespring m, for the purpose of keeping the member P in contact with themember R and pressing' it to the face of the member P with such forcethat it changes its position, and with it that ot' the Valves attachedto it, whenever it passes the center of the shaft that carries thevalves. The other end of the rod Z is so journaled or loosely suspendedin the wall o1, as to be capable of a vertical movement with the piston`The operation of my hydraulic engine is as follows: `Wateris introducedfrom the supply or main pipe through suitable connections into thecharge-compartment of the valve-chamber K, as indicated by the arrows inFigs. 3 and 5; thence into the an'te-water-chamber I', passing throughport I), as indicated by the arrow in Fig. 2, which forces up thepiston-head pro'- vided with the coupling until the member P acts uponthe inclined face of the member R, the valve closing the passa ge-wayand openin g the other passa ge-way.

reverses the direction `ofthe piston-head, which begins to descend,owing to the water passing upwardly through the passage-way G and talling upon the piston-head. The water thatfor'ced up the piston-head iiowsout of the cylinder through the same opening into the ante-waterchainberI, thence down the discharge passageway, which .is now open, into thedischarge This movement of the valves changes the course of the waterandr valve-chamber,and through the Waste-pipe on the opposite side ofthe induction-passage, as indicated by the arrow in Fig. 3. In this wayacontinuous reciprocating motion is imparted to the piston-head.

Fig. 2 ofthe drawings shows the water being emitted from above and thepiston-head ascending.

From this explanation it will be perceived that the inductionpassage-ways serve also as eduction passage-ways for the water that isto sav,the water is vdischarged from the cylinder through the saineopenings through which it was forced.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a hydraulic motor, the combination, with a reciprocating hollowpiston-rod, of a coupling-rod having at its lower end a wedgeshapedmember acting against a member attached vto the shaft carrying thevalves, for the purpose stated.

2. In a hydraulic motor, the combination, with a reciprocating hollowpiston-rod, ot' a coupling-rod having at its lower end a pivotedwedge-shaped member provided with a notch or recess to receive one endof a spring-rod, for the purpose stated.

'3. rI he two sets of valves connected to a shaft common to both, -toinsure their simultaneous movements, substantially as described, and forthe purpose set forth.

' 4. In a hydraulic motor, the combination of the reciprocating hollowpiston-rod, couplingrod 'with the wedge-shaped member,compressing-spring rod, shaft with acting member, and the two sets ot"valves, substantially as described.

In testimony whereof I have hereunto subscribed my'name.
